What is the volume of air that cannot be exhaled from the lungs even during a maximal expiration.
What cells produces lipase?
What organ are these cells in?
acinar cells (small amounts are also produced by the salivary glands and the chief cells of the gastric gland)
Label cells and their function
Where in the alimentary canal are enzymes denatured, and why?
Enzymes that work in a neutral pH are denatured once they enter the stomach, due to its low pH. Stomach enzymes are denatured when they move to the duodenum, where the pH is much higher in comparison to the stomach.
Occurs between the blood and tissues, and involves oxygen unloading (leaving the blood) and carbon dioxide loading (entering the blood).
In order for lipid digestion to be effective, must be present
Explain the difference between the basal layer of the endometrium and the functional layer.
The basal layer of the endometrium is the deeper layer that contains the stem cells that allow the endometrium to regrow. Its thickness is fairly constant and it is not shed during menstruation. The functional layer is the superficial layer that grows and changes in response to hormone levels. Its thickness varies significantly during the uterine cycle and it is shed during menstruation.
last one is active phase ovary
What organs/cells produce amylase?
salivary glands and acinar cells of the exocrine pancreas
What cells produce pepsin?
chief cells of the gastric gland
Name the typical substances found in the urine of a healthy person
water; ions such as sodium, potassium, chloride, and calcium; metabolic wastes such as creatinine and urea
Label A, B, & C
B: cricoid cartilage
C: arytenoid cartilage
What does it mean to say that a protein/enzyme has become denatured?
If a protein/enzyme is denatured, it loses its three-dimensional structure. In the case of proteins in food material, this makes them easier to digest. In the case of enzymes, this makes them non-functional.
Enzymes that are denatured are:
a. completely nonfunctional
c. slightly impaired in function
b. completely functional
d. more efficient at digestion
a. completely nonfunctional
What secretions contain amylase?
Saliva, pancreatic juice
Name the main location where lipase is active.
The ___________ _____________________ is/are the chemical(s) that are present in solution after a chemical reaction involving an enzyme is completed.
Explain the relationship between thoracic cavity volume and intrapulmonary pressure.
Volume and pressure are inversely proportional – as volume increases, pressure decreases, and vice versa.
Match each of enzyme to its substrate and end product(s). Each enzyme will match to two letters.
The part of this organ that produces lipase is the _______ part of the organ.
